let r be a g-graded ring and m be a g-graded r-module. in this article, we introduce the concept of graded weakly classical prime submodules and give some properties of such submodules.

MOTIVATION Most biological sequences contain compositionally biased segments in which one or more residue types are significantly overrepresented. The function and evolution of these segments are poorly understood. Usually, all types of compositionally biased segments are masked and ignored during sequence analysis. However, it has been shown for a number of proteins that biased segments that c...

We have investigated the correlation between structural and defect properties, optical performance of GeSn/SiGeSn multi-quantum well (MQW) structures as a function number QWs. Our results show that significant diffusion intermixing occur at interfaces during sample growth. The is more pronounced larger depths below surface where Sn Si composition profile in QWs layers undergoes transition from ...

CuInSe2 and CuInS2 form a continuous solid solution in which the optical bandgap varies from 1.0 to 1.55 eV [1]. By reacting CuInSe2 films in a flowing H2S/Ar atmosphere, the films can be completely converted to CuInS2 or converted to a graded CuIn(Se1-ySy)2 film, depending on processing conditions. A phenomenological model of the reaction/diffusion process is presented wherein H2S reacts with ...

In this paper, we propose a new dual gated trench power MOSFET with strained Si channel using the Si0.8Ge0.2 base and graded strained Si accumulation region using compositionally graded Si1-xGex buffer (x varying from 0 to 0.2 from the drift region to the base region) in drift region. We show that the introduction of strain in channel and accumulation region results in about 10% improvement in ...

Compositionally graded glass-filled epoxy sheets with edge cracks initially along the gradient are studied under dynamic loading conditions. Specimens with monotonically varying volume fraction of reinforcement are subjected to mixed-mode loading by eccentric impact relative to the crack plane. The optical method of Coherent Gradient Sensing and high-speed photography are used to map transient ...
